Basic circuit for pinball


#1

Hi we are looking at making a small pinball toy with yr 8’s 9V- A3 size and are hoping someone can point us in right direction as to a simple circuit that lights up and makes a noise. We have the skills to make the components but little idea with electronics that are priced so we can run the program with 150 kids. Maybe under $8 for circuit. Any help would be much appreciated.
